To all wliom it may concern:

-Be it known that I, ERNEST G. DANN, a citizen of the United States, residing at -.Chicago, in the county of Cook and State of 6 Illino s, have invented certain new and useful Improvements in Book-Holders, of

which the following is a specification.

My invention relates to a book-holder for I holding a dictionary or "other large book in 10, such a manner that the book may be opened and closed without removal from the holder.

The invention has for one of its rincipal objects to provide a book or dictionary stand on. holder which-may be constructed entirely of metal, and preferably to a large extent of sheet metal and tubing.

Another primary object of the invention is to construct the folding leaves of the device which sustain the book when 0 mi and which lie against the covers of t e book ,when closed,so thatthe weight of the book itself holds these leaves in their upright or closed position, thus eliminating the springs which are usual devices of this general character and which have always provena con-. p I

Flg. 13 a fragmentary view ofpneyof e;

stant source of trouble.

Another object of the invention is to pro vide a device of this sort which by simple mani pulation may be adjusted to books of difierent thicknesses, in which the height of thedeyice may be varied and in which the entang es.

qfurther. object of the invention is to.

85 provide newand im rovcd device of this character ,consistin o a few sim 1e arts V p p .of the drawings, 20 mdicatw a which-can be. cheaply manufactured, and which; can, be easily .,.assembled and" taken facilitated.

-, The invention ,has .for further objects such. other newand improved; constructions, arra-n ements, and. devices in book-holders .5apart,= 0 that the shipment of the device is particularly set ;forth in the claims .apended thereto. a

sleeve-like portions 22 'whichfernbrace' the standard, and are clamped thereto ,by opening;

collar 23 which hasthe threads I, for the set-screw The lower ends oi the.

N sleeve-like portions 22 are formed withfthe hooks 25 which extend into" 'slots: 26 i'ina 'disk 27 which latter has thecentra i ieves hi as e tsse It will be understood that the legs are hooked into the disk 27 before their upper ends are engaged by the collar 23. This arrangement, obviously, is "such that any weight placed upon the standard tends to increase the grip between the standard and its supporting legs.

Inthe upper end of the standard is rotatably mounted a head composed of two half sleeves 28 terminating in the convexed disks 29, the upper edges of which have a fluted conformation 30. Ribs 31 engage the upper edge of the tubular standard. The two members forming the head are preferably stamped out of sheet metal.

The disks have the central perforations 32 and are clamped together by the bolt 33' and wing-nut 34. The disks 29 are designed to clamp between them the ends 35 of a yoke member-36 which is designed to provide a slide-way for the brackets 37 to which are hinged the book-sustaining leaves 38. The Lyoke member is preferably formed of a single strip of sheet metal bent so as to fOilH a sort of box, the ends of which have openings through which extend, from opposite directions, the brackets 37. The part-s of the yoke forming the ends of the box or slide-way may be formed with the lugs 39, constituting guides and bearings for the brackets. The back of the yoke is preferably left-open and the ends of the brackets are secured together at any relative adjustment, arid to the yoke by means of the set-screw 40 which extends through a threaded pe forat-ion in one of the brackets, and bears against the other bracket. A finished appearance may be given to the front of the yoke by forming the same with the part 41 which is bent down as shown particularly in Figs. 3 and 4, so as to close the yoke. at this side.- The ends 35 of the sheet of metal forming the yoke are preferably in the form of disks of the same diameter as the disks 29 between which they are clamped. Thedisks 35 are formed with the, ribs 42 which are engaged by one i or other of the corresponding pairs of radial grooves at the edges of the disks 29, when the latter are clamped upon the disks By this means the book -sustaining leaves may be given any desired inclination by adjusting the position of the yoke. It

will be seen that when the disks 29 arch clamped together by. means of the bolt 33 and wingnut 34, the half sleeves 28 will have a tendency to spread a; trifle, the purpose of which is to cause them to bear against the inner surface of standard 20,.

sufficiently to prevent the book-holding portion .of the device from being too easily slipped out of the standard. The frictional enga ement of the half sleeves with the stan ard is not, however, intended to be enough to prevent the book' and its supportor off-set portions 48 terminating in the ears tions are extended between the standard 20 ing means from being turned on the standard.

The brackets 37 are preferably made of simple metal bars bent to the form shown.

The book-sustaining leaves, I prefer to make of single pieces of sheet metal, with their forward edges 43 turned at right ani gles to the' 'planes of the leaves so as to form a rest. for the edges of the book. The leaves are hinged to the brackets inwardly of the inner or adjacent margins of the leaves, and these inner or adjacent margins are formed with the preferably curved ofi-set 'portions' 4.4;, terminating, preferably in the beads or rolled portions 45. This construction of the leaves enables me to entirely do away with the spring devices ordinarily used in dietionary "holders to hold the leaves against the covers:- of the book when the book is closed. In my device the weight of the book, the back 9f which bears against the off-set portions 44, keeps the leaves in upright position and closely pressed against the covers of the book when the latter is .closed. Obviously, the weight of the bdok, when the book is open, is so distributed as to keep the leaves outspread. By eliminating the springs which are usual to devices of this class, my improved form of book-holder is A simplified in, its construction, and itsoperation. made fnuch more positive and accurate. The device likewise becomes much more durable, as in the ordinary form of dictionary holders it is the springs which are always getting out of order and becoming worn out.

While I prefer to construct the leaves of sheet metal, it is obvious that the same principle of construction might be applied to leaves constructed from other material. The leaves 38 are hinged to the brackets 37, preferably by means of the sheet metal hinge plates 46 secured to the leaves 38 by. rivets 47, and which are formed with't-he raised 49, between which, on each of the plates, extends the end of one of the brackets. 37. The edge 50 ofthe raised portion 48 forms astop which comes against the bracket 37 so as to limit the opening movement of the leaf. If desired, the stand may be provided with a shelf -51 consisting of a single sheet of metal with its ends turned up as shown at 52, the shelf having the central opening. for the standard 20. In order to keep the shelf from tilting the metal is not entirely cut away when the openingfor the standard is made, but instead, portions of each, 53, are struck up by stamping, and these porand the collar 23, as is best shown in Fig. 7.

The 0 eration of the device, as above described, 1s as follows: The device is adjusted for books of different widths bymaking a proper adjustment between the brackets 37731 eegs,442

The book, considering it as open, may be held horizontally or may be tilted up at any desired angle by means of the ad ustment effected between the disks 29 and the disks 35. The bookmay be turned freely on thestand, but thefrictlonal engagement between thehalf sleeves 28 and-the inner surface of standard 20 issuflicient todo away wit-h the necessity; of any stop or fastenin means between t head and the standar When the:- book is, to be used, it may be opened at any page and its weight will hold it 0 en. .The closing of the book causes the ack of thebinding to bear against the beads45, and this closes the leaves 37 against the covers of the book. In its closed position I the book is, therefore, sustained upon the curved or off-set portions 44 of the leaves. When the stand is to be shipped it may be packed into very, smallcompass by detach-- mg the legs from .the standard, removing the shelf-51 from the standard, and like- 'wise therotating head supporting the leaf brackets. The brackets themselves may be removed-from-the yoke, if desired. When the book is opened the rolled portions 45 ofthe leaves bear against theback of the binding and keep it from sagging. 'Ilhese rolls 11 Fig. '14 I have shown a substitute. for the standard. In this case the book-hold ing portions of, the device (the head consistin of the half sleeves 28 and the disks 29 alone being shown) are sustained on a bracket 54: consisting of a pieceof bent tubing, one end ofwhich carries the head 2829 and the other end of which extends into the'socket 55 of a bracket 56, adapted to be attached to a desk or table.

In Fig. 15 I have shown a modified construction of head adapted to be. used either with the standard '20 or with the bracket This head consists of a hollow malleable casting 57 havin a shank 58, which extends into the tubufar standard or 'desk bracket, the brackets 59 extendingfrom oppositesides through the perforation in the casting and being held at difierent adjustments-"by means of the set-screw 60 which is threaded-through the casting. One of the brackets preferably has the groove. 61 and the set-screw 60 has two or more grooves 62.

the other is formed so as to fit into this groove. The bracket primarily engaged by which receive the end of the set-screw at different inclinations of the device. The form of leaf and binge is thesame as above de-. scribed.
